我有一个“Pending Records Page”，我想计算所有待处理的记录。例如，我想在我的主页中添加“您有（记录数量）新的待审记录”我想在我的页面中添加该记录。就像在Facebook一样。从字面上看，它就像通知消息:)例如，我想在我的主页上显示“您有23个新的待定记录”。这是什么代码？请帮忙。在GridView中计数记录并显示标签消息
下面是我的主页的屏幕截图。我编辑了油漆。您可以看到我想要显示的标签文字信息。
Here'e我对我的等待记录页面代码：

<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
<%@ Import Namespace= "System.Data.OleDb" %>
